SWAP command request :)

[ampos]

Can we have a SWAP command? It interchange the value of 2 variables:

Code (glbasic) Select Expand

function swap: a,b
   local temp
   temp=a
   a=b
   b=temp
endfunction




Yeah, Im lazy

Hmm . . . now if we had function overloading this could be possible to do on our own . . .  !
Even for TYPES!

Truth is, you now have that command.

OK, I'll add a SWAP command.
Will it impact code? I mean "SWAP" might have been used as a variable in old code).

OK, I'll add a SWAP command.

lol really? was sure this was just joking... A new command for something you can do with 3 lines of code? Will your command be faster than doing this by myself? Otherwise I wont see a reason for adding such a command, werent you always trying to keep the number of available commands as low as possible?

Actually I think it would make for neater code, especially if you were doing card shuffling in a loop, save calling a function. Not that it would be quicker but would be neater :~)

This is cool for not using a temp variable...

Code (glbasic) Select Expand

a% = bXOR(a%,b%) ; b% = bXOR(b%,a%) ; a% = bXOR(a%,b%)

as a function...

Code (glbasic) Select Expand


FUNCTION Swap: BYREF SwapValue1%, BYREF SwapValue2%
SwapValue1% = bXOR(SwapValue1%,SwapValue2%)
SwapValue2% = bXOR(SwapValue2%,SwapValue1%)
SwapValue1% = bXOR(SwapValue1%,SwapValue2%)
ENDFUNCTION

Code (glbasic) Select Expand


FUNCTION swap: BYREF a, BYREF b
    LOCAL temp
    temp = a
    a = b
    b=temp
ENDFUNCTION


Should work, right? Having a fewer so might be thinking strange. Untested :-)

my SWAP command is a template, working for any object type.
